8 VINE: NOTES ON POLYZOA FOUND AT CLEETHORPES. 
Genus BICELLARIA Blainville. 
7. Bicellaria ciliata Linnzus. 
B.M.P., p. 68, pl. viii., figs. 1-5. 
Since the paper was written I have found a Sages of this 
beautiful species, adherent to Plocamium. 
Genus CELLARIA Lamouroux (part). 
= SALICORNARIA Cuvier. 
8. Cellaria fistulosa L. 
B.M.P., p. 106, pl. xiii., figs. 1-4. - 
A small but very perfect Zoarium of this species I found in 
my 1879 gathering. It was nestling in the bulky rootlets of 
Flustra foliacea, in company with Scrupocellaria scruposa. 
Hincks does not give Scarborough as a locality for this species, 
yet I have had sent to me a few forms from that neigh- 
bourhood as Salicornaria farciminotdes Johnst. 
Genus FLUSTRA L. 
9. tapers foliacea L. 
, p- 115, pl. xvi., figs. 1 to 1b. 
ie my 1875 gathering this form was rather stunted in growth, 
and the segments were very narrow; but in 1879 the normal 
form was abundant in the débris. To what causes may we 
ascribe the tendency to decay in examples of this species? 
Examples gathered in 1875 are well preserved and firm to the 
touch, whilst those gathered at the later date crumble to pieces 
if indelicately handled. 
10. Flustra securifrons Pallas. 
B.M.P., p. 120, pl. xvi., figs. 2-3. 
I was fortunate in securing a few really good tufts of this 
species in 1875. It may be common at Cleethorpes, but 
I have not gathered examples since. 
Genus MEMBRANIPORA Blainville. 
11. Membranipora reticulum L. (Jelly, p. 162). 
= Millepora reticulum L., Syst. Nat., ed. 12, 1284. 
= Membranipora lacroixit Hincks. 
B.M.P., p. 129, pl. xvii., figs. 5-8. 
Generally I have followed Hincks, but in the present case 
perhaps it is best to break the rule in favour of priority. Those 
who wish to investigate the case further will be able to do so 
even when accepting the decision of Miss Jelly (Synon. Cata-
